This class begins the unit on evolution, covering how life itself began. To start we will cover the three main hypotheses, Louis Pasteur, etc. then we will make a pros and cons list to compare and contrast them.
Opening: To begin this class the students will have a free write on the question on the board “How did life begin?” they will write for about 10 minutes and then we will begin the lesson.
-What was the earth like in the beginning?
-What kind of elements are present in the cell?
-Were these elements present on the early earth?
Activities: The students will take notes on the powerpoint I have created. The powerpoint covers the three different hypotheses about how life began. It also includes the important names and dates of the experiments that either proved or disproved these theories. After this the students will discuss in their groups which hypothesis they believe is most accurate, then as a class we will report out and create a pros and cons list of the three hypotheses.
-note taking session
-student groups of 3-4 to discuss the hypotheses
-groups report out on what they have discussed
-class will make a pros and cons list with students coming up from each group to list ideas
Closing: Finally we will as a class brainstorm different ideas as to how life began. For homework the students will find and summarize one article on the subject of the origin of life.
-Which hypothesis is most likely to have happened?
-How do we know a hypothesis is credible? -Could there be another explanation?
Assessment Notes: There will be no formal assessment for this lesson.
